DETROIT — Nissan is cutting prices on seven of its 18 models in the U.S., hoping its cars and trucks will show up in more Internet searches by shoppers.

The price cuts vary with the amount of equipment on each model. They run from 2.7 percent, or $580, on the top-selling Altima midsize car to 10.7 percent, or $4,400, on the Armada big SUV. Executives are under pressure to sell more cars, with Nissan's CEO targeting a 10 percent U.S. market share within three years.
